What it is

Leavening yeast is a single-celled microorganism, a type of fungus. It is commonly grown on molasses or grain-based media. Yeast is used to make bread and other baked goods rise by producing carbon dioxide gas during fermentation.

Why it's used

Yeast is primarily used as a leavening agent in baking, causing dough to expand and become lighter. It is found in a wide variety of baked goods, including bread, pizza crusts, and pastries. It also contributes to the flavor and aroma of these products.

Health notes

Leavening yeast is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food. It is a natural source of B vitamins and protein. International bodies like JECFA and EFSA have evaluated yeast and its components. No significant health concerns are associated with typical consumption levels.

Allergen info

Leavening yeast is not derived from any of the 9 FDA major allergens. It does not contain gluten.
